Post catalyst oxygen sensor diagnostic |
摘要 |
An engine exhaust sensor diagnostic system for an exhaust system including a catalyst and a post-catalyst oxygen sensor includes a first module that calculates a total integrated area based on a signal generated by the post-catalyst oxygen sensor. A second module compares the total integrated area to a threshold integrated area and generates a pass status signal when the total integrated area is less than the threshold integrated area.
